Suppose you want to test the claim that mu is not equal to 3.5. Given a sample size of n = 31 and a level of significance of alpha = 0.10 when should you reject Ho?
A) Reject Ho if the standardized test statistic is greater than 2.575 or less than 2.575.
B) Reject Ho if the standardized test statistic is greater than 1.96 or less than 1.96
C) Reject Ho if the standardized test statistic is greater than 2.33 or less than 2.33
D) Reject Ho if the standardized test statistic is greater than 1.645 or less than 1.645.

Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the Z score = .05 in the smaller area.
